MACHINE FOR COVERING WIRE.

SPECIFICATION forming part of Letters Patent No. 416,254, dated December 3, 1889.

Application filed October 24., 1888- S erial No. 289,006. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. COOLEY, a citizen of the United States, residing in Montreal, in the Province of Quebec, Canada,have invented certain new and useful Improvements in Machines for Covering ire, of which the following is a specification.

My invention relates to wireinsulatin g machines of that particular class in which the wire is fed through the hollow spindles upon which the bobbins containing the insulating thread or yarn are mounted, and which are adapted forwinding or filling the bobbin with the insulating-yarn, and also for winding said yarn upon the wire, without removing the bobbins from the machine or from the position in which they are wound.

The invention embraces electrical apparatus for stopping the machine whenever the yarn breaks either in the insulating operation or in the bobbin-winding operation.

The broad idea of stopping a winding-machine when the thread breaks I do not claim as my invention; but the particular manner of carrying out such feature will be embraced in claims hereto appended.

Referring to the accompanying drawings, Figure 1 represents a front elevation of the machine adapted to run two bobbins simultaneously. In this view the upperportion of the machine is shown as filling a bobbin, while the lower part is shown as winding the yarn upon the Wire. It will be understood, however, that these two operations will not be carried on simultaneously, but that either one of them may be accomplished on both parts of the machine simultaneously. Fig. 2 represents a detail view of a part of the apparatus shown in Fig. 1; and Fig. 3 represents a side or end elevation of the apparatus, the windingspindles being removed, the object of this being simply to show the threadguiding mechanism for winding the bobbins and the apparatus for operating the clutch, the clutch being shown disengaged. Fig. 4. represents a detail of the circuit-closing mechanism operated upon the breaking of a thread.

For the sake of convenience of illustration, the magnet controlling the clutch is shown in Fig. 3 reversed in position relatively to the retards its movement.

machine.

Motion is imparted to the machine from a horizontal shaft A by means of belt a, which makes a quarter-turn over guide-pulleys a and thence around the loose portion or member B of a friction-clutch B. This clutch controls the main shaft C of the machine and may be operated either automatically by electricity or by hand. A lever I), having a handle at its outer end, is pivoted to the frame at b and to a sleeve around the lower end of the shaft, said sleeve bearing freely against the loose portion of the clutch. The lever has a shoulder b which, when the machine is running, rests upon the upper end of a pivoted arm 12 thus holding the loose member up in contact with the tight -member B The machine is adapted to run at a high rate of speed, and its momentum is sufficient to keep it in motion some time after the clutch becomes disengaged. I have therefore provided an automatic brake mechanism consisting of the weighted disk I), located loosely on the shaft above the light clutch and adapted to slide thereon. This disk is surrounded by a strap-lever which is connected with it at the points If. The straplever is pivoted at b to the frame and is pivotally connected with link I), which latter is hinged to lever 11. hen the clutch is engaged, the disk is held'out of contact with the tight part of the clutch; but when it becomes disengaged by the lever 12 dropping the disk falls upon the tight portion of the clutch and \Vhile this brake is ordinarily automatic in its operation, by manipulating the lever b by hand the motion of the machine may be bridled to any degree.

The winding mechanism is mounted in a suit. ble frame D, having in the instance shown three platforms K K K for supporting the different parts of the apparatus. The upper platform simply supports a drum or wire-feeding pulley K, while the two platforms below support mechanisms which are nearly identical with each other. It will therefore only be necessary to describe in detail one of the mechanisms. The shaft C extends to the full length of the machine and is provided with pinions c, which drive, through intermediate gearing, the tubularbobbin-shafts,which have their hearing in the brackets C The intermediate gearing in one case preferably embraces one more pinion than in the other, so that the spindles will be turned in opposite directions. The bobbins ll are mounted loosely upon their shafts and restnormally upon the journal-boxes t'oruicd in the brackets G I will first describe the mechanism for or manner of filling the bobbins. This mechan ism is shown in the upper part of the ma chine. A vertically-rcciprocating rod E is moved by the cam-wheel E. Fig. 3.) This is a heart-shaped cam, upon the periphery of which rests the lever e, which is connected with the rod E. The rotation of the cam causes the reciprocation of the rod. Motion is imparted to this cam through a worm R and gear from the main shaft C. To the rod E is adjustably attached by means of a friction-tight hub a lateral arm f, carrying a guide or frame f at its inner end, which stands quite close to the bobbin. This frame is provided with weights 1*, having hooks which pass over the strands which lead from the supplying-bobhins M to the spindle. The books suspend the weights, and when a thread breaks said weights or weight is al* lowed to drop, closing an electric circuit by falling upon two terminals fixed in the arm supporting the weights, as will be readily seen in Fig. The reciprocating movement of the rod E carries the strands up and down in front of: the bobbins, thus forming an oven winding. \Vhen a bobbin is being wound, the intermediate gcarin g between shaft i and the spindle is broken by the removal of one of the pinions, and the bobbin then revolvcd through a small belt g, which passes over grooved pulleys c c on the end of the bobbin and upon shaft C.

It should be stated that the bobbins are loose upon their bearings, so that the belt g may turn them for filling purposes, and also in order that they may slowly revolve in the operation of winding the yarn upon the wire.

Returning to the manner of closing the electric circuit when one of the weights falls, it will be seen that the circuitleads from battery 0 through magnet 0, thence to contacts i 2 and back to battery. A branch circuit runs to the contacts adjacentto the suspended weights. The armature of this magnet is connected with the pivoted lever Zr, which supports the clutclrlever 11. When a weight f drops and closes the circuit, the armature is attracted and the support of the arm i) is removed, thus allowing the loose clutch to drop out of contact with the tight clutch and stopping the machine. The electric circuit just described also includes a pair of contacts 0 0, one of which is stationary and the other connected with the lover I).

, \Vhen this lever drops, the circuit through (Shown best in waste of battery. \Vhcn the bobbins have been wound, the arm f, with its attachments, is removed or drawn back and the machine threaded for winding upon the wire.

Referring now to the mechanism in the lower part of the machii'le, it will be seen that the yarn 71. passes through an eye in one of the fliers II, thence over apivoted springhook it", thence through a guide-eye 71, and finally to the winding-head h". This head and the fliers are of the usual construction and need not be described in detail herein. To start the winding operation now, the displaced pinion which was removed for the p u rpose of tillin the bobbin is replaced and belt removed. The clutch then being thrown in, the gearing turns the spindle, and the fliers carry the thread around, winding it on the wire in opposite directions.

d 'hen for any reason the thread breaks, the pivoted spring-arm h is thrown outward by centrifugal force and strikes the pivoted circuit-closing arm 2?, which drops upon the corresponding contact i and closes the elcctrio circuit through the magnet, thus opera-tingthe clutch and stopping the machine. This construction is best shown in Fig.

The wire, after passing fromv its reel over guide-pulley N, passes up through tension device 71, thence through the two spools, and twice around the feed-druni K. This drum is turned at a regular spcedby means of gearing o 'ierated from the worm R upon shaft The said worm rotates a pinion on the shaftcarrying cam E. This pinion in turn drives, through intcrn'icdiate gears and shaft, a pinion which meshes with a gear lined to the drum-shaft, as shown.

llaving described my invention, I claim- 1. In a winding-machine, a reciprocating rod carrying thread-guides and electric contacts, in combination with a rocking lever and a cam for reciprocating said rod, threadguides, and contacts, whereby the relative positions of the guides and contacts is constantly the same.
